How to pull the air with new batteries. How to lower the air from the heating battery. Air traffic removal methods

In the process of operation of the heating system, it is often necessary to strengthen excess air located inside the contour. In addition, to avoid air-related problems in the pipeline, it is necessary to take measures aimed at preventing air from entering the system in the future. On how to pull the air from the battery and not allow him to get there again, and it will be discussed in this article.

Driving air in the heating system

First of all, it is necessary to deal with what danger to the heating system represents air in it. And the problem is quite simple - air traffic jams in the heating system to completely paralyze the operation of the heating system throughout its length or in a separate section.

It's all the case in a small pressure drop at the inlet and outlet of the system - this value usually does not exceed 0.2 kgf / cm. This pressure is missing in order to level the difference in the density level of water and air. Because of this, the upper part of the riser is completely filled with air, and the coolant simply cannot circulate. As a result, the apartment remains without heating, and upon the occurrence of cold, the system plot completely freezes.

On the phenomena described above, the problem does not end. In high-rise buildings built in Soviet times, pipes from ordinary steel are still used. Humidity in the heating system is high, and black steel in such conditions when contacting the air begins to collapse in a multiple accelerated pace. The result is predictable - at some point the system comes into a completely inoperable state. So that this does not occur, you will have to understand how to pull the air from the heating system.

Causes of air appearance in batteries

At first glance, it may seem that the air in batteries is simply nowhere to take, because the heating system is in the filled state all year round. It is nominally so it is, as they say all existing standards - but in practice it is impossible to maintain the system's tightness of the system all the time, and over time it provokes the removal of air tube in the heating system.

Air appears in batteries due to the following factors:

Seasonal repair and preventive work. At least once a year, the heating system has to be checked and, if necessary, repair. According to the instructions, you need to fill out the contour after the replacement of each design element - but water will go too much, so housing and utilities do not go to such costs.
Replacing heating devices. Another reason for the appearance of air in radiators is to replace them or transfer apartments with residents. Of course, each reset of the riser can cause him to make it.
Physical processes. When all the valves are closed, and the pipeline is cooled, the volume of the coolant in it decreases. If in such a situation, open at least one valve - batteries will be delivered, and have to think how to put air from the battery.
Damage to system elements. The weakest link in the heating systems of apartment buildings are cast-iron radiators, which, when disconnecting heating, begin to flow due to thermal expansion. At some point, it is necessary to solve a serious problem - change all the batteries in the entrance or simply reset the system before the heating season.

Methods of air booming

To descend the air from the heating system, several ways are used, choose from which you need depending on two factors:

Heating configuration. Since there are differences in the lower and upper filling systems, then the air of them is poured in different ways.
Attitude to the heating system. The tenants of the apartments descend the air from the batteries at all. Not as professional mechanisaries do - too different tasks requiring different solutions.

Before removing air from the heating system, you need to consider all the ways in more detail.

Nizhny bottling with user access

A distinctive feature of the lower bottling is the pairs of connecting heating. The rosters of the supply and returns with such a scheme are located in the basement of the building, and the valves are located between them. The valves are installed or plugs, or cranes, allowing water when necessary.

Available in the risers of the system with lower bottles is squeezed into the upper sections of pairs of connected risers. On the upper floor (as a rule, in apartments, but sometimes in the attic room) between the risers there is a jumper, near which the crane of Maevsky is installed, allowing you to burst air from the system.

Knowing how to drive an air stopper from the heating system, it is necessary first of all residents of apartments on the upper floors:

The crane turns 180 degrees, and air will start out with hissing;
When water will be leaked from the radiator, the crane must be closed.

For accommodation on any other floor, it will be enough to ask the neighbors from above to put air in free time. In the event that for some reason it is impossible to negotiate with neighbors, it will be necessary to submit an appropriate application to the local housing organization. The main thing is to ensure that the application is adopted in all the rules, and then in the event of problems with heating it will be possible to further require recalculation.

Lower filling with administrator access - removal of air traffic

It is one thing if the problem can be solved only from my own apartment or with the help of access to specialists. Another thing - if the role of a specialist can be played independently, for example, getting access to the basement.

The solution to the problem in this case is as follows:

Before removing the air from the heating system, it must be pinned it, for which the heating valve is first closed and the sewage reset under it opens;
After performing previous actions, the system needs to be given about 5-10 minutes to air output;
If the desired effect has not been reached, the system needs to be mixed in the opposite direction;
After the air booming, it is necessary to close the reset and return all the valves to the starting position so that the heating circuit continues to function in normal mode.

Separate risers with which there are problems, too, can be mixed with a base level. To do this, it is enough to overlap the valve of one of the connected risers and open the reset. The probability of successful air bleeding in this case is sufficiently high, and if one of the risers is used as idling, then work is necessarily crowned with success.

Even if plugs are installed instead of discharges on the risers, there are a pair of ways to get rid of air traffic jams in the heating system:

The first option is to block both risers, reset them, and then change one of the plugs on the ball mama carvings. Of course, for such an option, the crane itself will be required - but its cost is small, and such costs certainly stand that the heating system can continue to work.
For the second option, you need to close the valves located on risers, and then unscrew one plug. The riser is translated into the reset mode, stops, and then the previous operations are repeated in the reverse order. In this way, air booming can be used only at a coolant temperature below 45 degrees - otherwise a person performing this work can seriously burn.

Upper bottling with administrator access

If the building uses the upper bottling in the building, this means the following: The coolant feed point is in the attic, and the reverse contour is located in the basement. With this configuration, the risers are connected to the bottom and on top, while having the same functional load, therefore within one floors, the system supports equal temperature.

Behind the brief results, we can say the following - in the absence of experience and understanding how the heating system works in an apartment building, it is better not to think about how to strip the air from the radiator yourself. For example, with the upper rosy there is a considerable risk of infringement located on the upper floors of the apartments, so it is better to refer such work to specialists from the housing company.

How to lower the air from batteries in a private house

In private homes, there can also be a situation in which air will appear in the heating system. It is rather important not how the heating system in the private house is enjoyed, but how to get rid of unnecessary air. There is no universal solution to this problem - the heating of a private house is usually designed individually, so the collected design has a lot of its own nuances.

However, in all types of heating systems there are similar features that need to be studied before the air from the battery is:

If heating has a forced circulation, then special air lines are always installed near the pump (as a rule, they are located or before the pump, or directly in the boiler). Air in the system in the presence of such elements is most often due to their clogging.
Air removal valves can be installed directly on batteries, but only if they are located above the bottling point. If bottling is somewhere at the top level, the air valve must be sought at the uppermost point.
On all vertical bends of bottling there are own air workers. In their absence, the air will have to use one of the methods described above.

Before releaseing air from the battery, you need to make sure that the heating system is run correctly - sometimes the cause of its stop is covered in one of the plots of the valve.

Safety and preventive work

To avoid injury and other problems, you need to observe a number of rules when air bleed:

The core from the air valve is not unscrewed - the pressure of the heated coolant will not give it back back;
The body of the crane can also be turned out - threads are very simple, and eliminating the consequences of the flooding of the apartment is difficult;
Radiator corks can not be unscrewed even partially - back them not to return, and boiling water-pouring from radiators will bring a mass of negative emotions (read also: "What radiator tubes are better to use when installing heating radiators").

For accommodation on the top floor or in its own house, protective measures can be taken, which will continue not to think how to descend the air from the aluminum radiator:

In the autonomous heating system, radiators will be installed, using the bottom connection, so that the air does not affect his performance in the heating device;
At the top point of the riser or autonomous heating, you can install automatic air valves that will independently release all air batteries.

Conclusion

This article responds in detail on the question of how to correct air from the heating system. This task has a number of nuances and difficulties, so in the absence of confidence in our own power, it is best to entrust it with specialists or local housing management.

Most often, no problems arise. But sometimes suddenly in the house becomes cold or strange sounds arise in the heating radiator. What can it be? Unfortunately, in this case there is air in the heating system, which means that air is needed from there. Today you will learn how to do it without crane Maevsky.

Enforcement in the battery: what it is and how to determine

What is enforcement in the heating battery? Under this concept, air accumulation is meant, and most often in the upper part of the heating radiator. Such a situation becomes a problem and quite frequent for those who live in high-rise buildings on one of the last floors. The reasons for the occurrence of such trouble can be several:

Carrying out repair work on the site / in the neighboring floors. In case, in a residential square, work with heating pipes were carried out, the likelihood of a small air flow system was large.
There was a leakage of the coolant on some of the sites (which means immediate checking system to eliminate leakage).
Feature of the system of warm floors. The problem of the enforcement system is indeed a frequent pattern in the presence of a warm floor system, especially if it has a complicated scheme and many branches.

Pig-iron battery

In water having a high temperature, air is contained and the more often updated in the system, the higher the probability of a problem.
If the appearance of the air "traffic jam" coincides with the launch of the overall heating line - with a greater share of the probability, it is possible to say that it is the start of the system that caused recent.

Council. If you live in a private house, then, in principle, it is not necessary to get hard to worry about the enforcement of the system (if it is small), the fact is that in private heating systems most often the coolant changes extremely rarely, and it means that the air must be independently scribified within a few days.

Determine the presence of air "traffic jam" is simple enough. For example, if the water temperature in the battery has dropped sharply or the battery has become cold only partially, it may even start the bubble - all this is signs of delight.

Rest of air without crane Maevsky

On most home heating batteries, there is a special device that helps to simplify air blending task - or an automatic valve.

But here is the question: what to do, if such a device is simply missing on the battery? If you just like this picture before my eyes - most likely, in your home are installed. On such batteries, a simple plug is often installed, which was spinled on the pack-covered panel. In addition, it was also filled with a layer of paints during the staining of heating batteries.

Crane Maevsky

Remove it in order to access the heat carrier located in the system, it seems difficult. For this reason, the simplest way out of the situation can be considered an appeal to the neighbors from the last floor of the house (they will certainly have a crane of Maevsky on the battery). But if neighbors, for example, have left or you yourself are the tenant for the last floor and there is no crane? In this case, you will have to resort to the "Dedovsky" method of streaming air from the heating system.

So, you need to stock basic, bucket and plenty of rags. In addition, after all, after all, it's not to take this "barrier"), you will need an adjustable key to unscrew the plug and some kind of solvent for paint. Otherwise, you just can't move the plug with the "dead" point.

So, first apply to the place where the plug is installed, solvent and wait 15 minutes. After that, you carefully start moving the velocked key along the thread until the plug is fed. You will hear how the air starts to burst. When the sound drops (a sign of lack of air), be sure to turn the "Fumka" layer plug and insert it into place. If you wish, you can slightly paint the interface of the plug with the battery.

Council. Before starting work, it is advisable to block the riser for the safety of work, otherwise with a sufficiently cut jerk, you completely unscrew the cap and the water from the battery is no longer stopped.

You learned about how quickly and quite simply can be copped with the task of moving the air from the radiator of heating in the absence of the crane of Maevsky. Good luck!

Installing the crane on the battery: video

In the water in small quantities is dissolved oxygen.

However, over time, it can lead to great difficulties in the heating system.

And if you have at least one radiator in your apartment (or home), you must know how to pull the air from the heating battery. And you can do without a call to the wizard!

Enforcement, or an air plug - this accumulation of air at the top of the heating device (or pipeline).

In apartment buildings, the inhabitants of the last floors suffer especially from the problem.

The causes of convulsion can be several. We list the main:

Repair works (if manipulations were made with the pipeline, it leads to ingestion of the air system).
In urban apartments, it is difficult to put in the work of the Highway without traffic jams, because ideally, the system should be filled with water very slowly, with simultaneous blending.
Somewhere leakage (even a small leak on the junction should be immediately eliminated).
Difficulties often occur with the warm floors, if its branches are laid not strictly horizontally and at different heights.
In any water, with an increase in temperature, oxygen is released. In private houses over time, all air leaves, and if the coolant does not change, you can forget about the problem. But in the central heating of portions of the liquid is updated constantly.

If it is not at all possible to do everything with your own hands, you can leave a request to the company serving the house to send the masters.

But the work of the system usually takes two weeks, so it is not necessary to hurry up with complaints.

How to determine it?

Detect the plug easily, she will give themselves to know:

Batteries can start bullshit;
The temperature in the rooms will decrease without visible reasons;
Part of the radiator will warm up, while the other area will remain almost cold.

Lightly knock the metal object at the top of the radiator, and then compare the sound from the knock at the bottom of the device. Where a plug appeared, the sound will be more ringing, high.

What can heating enforcement?

The phenomenon paralyzes the operation of the system - the circulation is disturbed, which leads to overheating of individual sections of the heating system and insufficient warming of others.

Because of the long-term contact with oxygen, many metals are covered with a scale, subjected to destruction. Especially sensitive to the launch of the heating system aluminum radiators.

In private houses with forced circulation, the air is in contact with the circulation pump. The device's life is reduced.

How to lower the air from the battery

In the gravitational system of the private house, all bubbles themselves go through the expansion tank located at the top point.

In urban apartments, an air vent is installed on each radiator:

Manual (crane Maevsky).
Automatic valve.

Depending on what is established, the work technology will change.

Aluminum, bimetallic or cast iron

Aluminum - Not the most suitable material for heating. It actively enters chemical reactions and highlights hydrogen. But thanks to its humble price and good thermal conductivity, it is often used. To combat aluminum flaws, it is covered from the inside with a layer of special film. But over time, it ceases to act, and hydrogen begins to stand out inevitably.

Bimetallic radiators - Another invention, improving the quality of heating devices. Where contact with the coolant occurs, another metal is used here. And fins are made of aluminum.

If a thermostat is installed on the battery, it is necessary to simply periodically open and wait for the air. The process of blending air from bimetallic batteries does not differ from work with an aluminum radiator.

Natural air content in the system, during the season creates problems: cold radiators of heating, noise, with time corrosion of metal pipes begins. To avoid uncomfortable operation and extend the service life of steel wiring and heating blocks, the system is released from atmospheric plugs. Let's talk why they arise and which ways will get rid of them!

Installing the crane on the heating battery

Causes of air concentrations in the heating system

One condition for the accumulation of plugs is understandable - a long break in the work of the heating system. Other reasons are as follows:

Calculation of home wiring is made incorrectly. Not taken into account the slopes, inflection. Due to this, even a professionally designed system will contain a certain amount of air after turning on to work. It will certainly be formed and in some cases remaking the entire system.
Uneven filling system with a carrier. This happens in connection with unstable pressure in the pipeline, damage to the sections outside the entrance to the house or when working with interruptions. Filling with emptiness atmospheric masses occurs during the heating season if the carrier pressure value is low. Interests are used for steering.
Exactness of the pipeline. As a result of the operation of the heating system and, accordingly, the repair, replacement of areas on separate nozzles can be carried out negligently. The absence or insufficiency of the seal will lead to depressurization and due to the power of pressure, the fistula takes the air in the water circuit, accumulating it on the pipeline sections. Before removing the air plug, the pipeline is tested by the wash of the prepared emulsion.
Air traffic jams appear as a result of water heating. From the school year of physics, it is clear that heating, the air in the system of heating a private house or an apartment building expands and forms bubbles. Blowing, they produce air, which immediately accumulates.
No air intake devices or their inappropriate work. Air discharge valve from the heating system is the first to pay attention to, designing your own home heating. A closed system with an autonomous type heating unit in his own home should have a similar device on a boiler or furnace.

Scheme of self-removal of air traffic

The formation of traffic jams affects the connection to the system of heating of other water contours - boilers, warm floors. The level of finding additional devices is straightely different from the position of heating devices, which is why the appearance of the atmosphere is inevitable. To operate these types of heating, a watering circuit with a check valve is carried out, the pressure in the instrument systems will remain stable and the cork formation will not occur.

We remove the air stopper from aluminum and bimetallic battery

When the cause of the cluster is defined and eliminated, proceed to eliminate the airbroken. Before the air from the heating system, it is important to know how the coolant circulates is forcibly or naturally. This depends on the method of streamling mass. So:

Natural circulation

For such a system, a sufficient expansion tank at the top point - the feed pipe is paved to it under the slope upwards. To keep air from the heating system, each radiator is supplied with a slidder or crane of Maevsky to sequentially squeeze the mass towards the Baku, pre-emptied.

Forced circulation

In this case, the feed pipe has a bias down. It establishes trigger cranes, and the reverse is directed to the water plum so that in case of emergency measures, the air from the heating radiator was possible quickly for subsequent repairs.

Air Power Instruments from Heating System

Reset function have numerous cranes and trigger valves. The most common areas of private houses are as follows:

Crane Maevsky. In the documentation, it is indicated as an air needle radiator valve for heating. Required to relay the heating system. It consists of a brass housing containing a hole for the release and screw. Implement them using a special key or screwdriver turns counterclockwise. When the air will stop out from the system, the crane is closed until it stops. It is necessarily necessary to prepare the container for collecting water and the rag - it is thrown on the crane to avoid splashing on the walls of dirty water. Used pump is temporarily disabled.
The air vent is automatic. The principle of operation is to trigger the float built into the case - the air automatic valve itself is already at the point of the system. When air accumulates in the pipeline, the float is lowered, thereby opening a reset valve and removing it. After normalizing pressure, the mass of water presses the float again. To prevent the leakage of the carrier, the instrument body is equipped with a helical cap. The device is indispensable for compulsory circulation.

Installation of heating system in the house

Separator. "Advanced" Interests in the heating system. It is installed mainly in extended autonomous heating networks. Allows you to reset not only air, but also sludge - scale, dirt, sand and clay. It consists of two parts: a common cylinder housing with two outputs - the upper chamber for air and the bottom for solid garbage, and the filter grid, delaying air bubbles and their guide up, in the chamber. In order to lower the air from the battery, they open both cranes and clean the highway.

For high-quality work, the home network of heating, the masters are recommended to set several types of blending devices. For example, an automatic reset valve for heating is mounted on a boiler or furnaces - there is a stable pressure there. Radiators are equipped with cranes of Maevsky each. The collector is complemented by a separator.

Determination of delivered plot and removal of traffic jam: how to lower the air

There are several ways to determine air accumulation in the system. The main one is a cold area of \u200b\u200bthe network. In addition, the sound when climbing the call, rather than on pipes with normal water circulation. Characteristic noise - bouffaging and hiss - will prompt about the presence of air. So, when the site is defined, they are applied as follows:

An important condition: expel the air from the heating system is possible only in the direction of the coolant and from the point behind a certain area using the nearest crane of the Maevsky or other type of desontest.
Next, slowly open the air valve for heating, prepare the appropriate tools, tanks and rags and descend the air.
The control output is made a short-term inclusion of the circulation pump. After that, closed the crane, and the system operation goes as usual.

Thus, it turns out, remove the air from the heating system. Easy and independent work will take no more than an hour.

If the system is still aircraft

It also happens that the measures taken do not act, and remove the air from the heating system did not work. What to do in this case:

Try to move air accumulation from places located far from the valve of the slutter. To do this, raise the system temperature by increasing the dose of fuel. Accordingly grows pressure. The method is good, as it allows you to remove air surplus automatically through the valves, an expansion tank or an air collector for the heating system. At least, to fit the mass of air to the valve will be possible.
Shock method. Hammer acting on radiators, create media oscillations that move the plug. Experienced masters, this method helps to move the mass of the air to the right place.
Carefully. Heating will have to dismantle and collect anew. To do "smaller blood," disassemble from Italian manufacturers for such a goal is good, as they have prefabricated elements that can be accurate twisting. The radiators are disassembled, removing the accumulated sludge from them, and collect, using sealing gaskets. The method is available only to professionals and with permission from the serving company, as it is necessary to overlap the riser if it comes to an apartment building.

So, learning why the heating system is delivered, eliminate the cause and expel the accumulated masses are already easy - the process is understandable.

It is important to constantly subjected to the prevention of your own heating model so that in the future the operation is without such unpleasant affecting comfort, surprises.

To lower the air from the battery it is not difficult, the main thing is to study all the nuances!

Residents of private houses and inhabitants of urban apartments are regularly faced with the problem of delivered batteries. Especially often this phenomenon occurs at the beginning of the heating season or during repair work. Of course, you can call plumbing from the management company, but it may be possible to wait for quite a long time. How to pull the air from the battery yourself and restore the health of the heating system?

Signs of aerial traffic

It is possible to understand that air has accumulated in the battery, it is possible for several signs:

Uneven heating radiators. It may touch a separate battery or the entire heating system of the apartment. In the first case, the delivered part of the radiator will not be heated. In the second, the plug will interfere with the normal circulation of the coolant through the system, why some batteries will be hot, and others are significantly colder.
Hissing or bugger in radiators is a clear sign of the presence of an excessive air in them.

What is dangerous air in the battery?

Before you understand how to release air from the battery, it should be understood as he got there and what is dangerous.

In addition to reducing heating efficiency, air appearance in batteries may result in the following problems:

Metal from which radiators are made, with air contact more corrosion. Therefore, the service life of the heating system is significantly reduced.
The difference in the temperature of various elements of the pipeline can lead to its destruction.
The resource of the circulation application is significantly reduced. Under normal conditions, its bearings are in water, when air intake significantly increases friction, leading to the device breakdown.

Causes of reinstateness of batteries

The reasons for air entering the system can be several:

In an apartment building, it happens most often when the system is filling in the coolant. According to the rules, the process should be carried out quite slowly, with constant air blending, but in reality is not always the case.
Incomplete tightness of the heating system. In this case, you will have to burst the air constantly until the disadvantages are eliminated.
Conduct various kinds of repair work. If at least a partial palate pavement was produced, some amount of air will inevitably fall inside. Therefore, after such events, it is necessary to lower the air from the heating battery.
Low quality coolant: Increased content of air dissolved in water can lead to the formation of an air traffic jam.

Elimination of air traffic jam

Special valve, located usually on its end, will help to store air from the battery. In old models you will need a radiator key. In modern models, Maevsky crane is installed, to work with a simple screwdriver or a special small metal or plastic key, which can be bought in a business or construction store ..

The sequence of actions is as follows:

To the radiator you need to substitute a fairly roomy container. When air bleed from the battery, some kind of water will be set out. It is better to not allow it to hit the floor.
In the films and in life, you can observe the podplikovy water, wet from the head to the legs. Indeed, this operation may be accompanied by splashing water in the system under pressure. It is not only unpleasant, but can also harm the walls of the walls or furniture. It is quite simple to solve the problem: you need to hang on the valve with a rag that will delay all the splashes, and water quietly stalks in a bucket or a basin.
A key or screwdriver carefully unscrew the valve until the clear hiss of the outgoing air is heard.

As water starts, water will begin to drip. We must wait until it does not stick with a thin trickle. The crane can be closed as soon as the air will stop bubble in this jet. Usually this operation takes 5-7 minutes.

Council. If you do not want to repeat the air boom procedure too often, then follow the advice of professionals and take a minimum of 2-3 buckets of water. This will be guaranteed that the air from the radiator is completely removed.

Very convenient device - automatic air vent. Here the procedure takes place without any participation of a person: when air accumulates, the float is lowered closing the drain hole. After the breaking of the float returns to the place. An essential drawback of such devices is increased demands on the quality of the coolant. Therefore, in apartment buildings with centralized heating, they are rarely installed, as they quickly fail.

And if there is no shrink valve?

Sometimes there is no drain valve on the radiator. It usually concerns old cast iron batteries, where his role is played by the plug. In this case, the work is complicated, but not so much so that it is impossible to fulfill it yourself.

It is necessary to stock up with a gas or adjustable key, with which you can unscrew the plug.

Important! Be sure to overlap the access of the coolant to the radiator from the riser. This is done if the plug turns completely. The water pressure then simply will not allow it to insert it into place, and this will be wrapped by subloping of neighbors.

The main problem is that usually the plug prevents the thick layer of paint and hardened pacle. It is possible to solve it using kerosene or lubricant for threads. We apply it to the connection and wait for 15-20 minutes.
Gently turn the cap and descend the air in the same way as in the case of Maevsky's crane. Do not forget about the container for water and about a rag that prevents splashing.
When you twist the plugs, you should not forget to apply the seal on the thread, for example, FUM tape to eliminate the leakage of the battery in the future.

To facilitate this difficult task, many owners put a regular crane in the past in the past. He did not add aesthetics, but the procedure facilitated significantly.

In private houses, an expansion tank is used to eliminate air traffic jams. After the water descending, the faucet opens, and in most cases the plug disappears. If this did not happen, it is recommended to increase the temperature in the house so that the coolant boils. Then the problem of delighting will accurately disappear.

To ensure a guarantee, it is enough to carry out an excess air whipping procedure for all batteries twice. After that, the heating system will function normally.

Understanding how to pull the air from the heating system will help not stay in winter without heat

There are no cases when the radiators are suddenly stopped during the heating season. One of the reasons for the system failure is a air traffic jam, and then a problem arises before tenants, how to lower the air from the heating battery to restore the circulation. There are several effective ways to normalize heating and how to lower the air from the system. At the same time, the procedure should be determined depending on the type of heating system and the particular air accumulation site.

The appearance of air traffic jam

It is easy to find that a heating system has been formed in the heating system, easy enough. Signs of importing system:

in pipes and radiators, bubble sounds are heard;
batteries or do not warm at all, or heated only to half;
in some rooms it is hot, and in other heat does not pass.

It means that the air has become blamed everything, and how to pull it out from the heating system, you need to decide according to where it was accumulated. Air bubbles always accumulate in the upper part of the heating system, so most often cooled radiators in the premises on the last floor. To find the location of the air plug location, you need to consistently feel the feed pipeline and all batteries by checking the degree of their heating. Also advise to pull the pipe with a hammer and determine the sound where emptiness originated, but it should be done carefully, so as not to damage the paint layer on the pipes.

As a result, finding a problem place, you can already choose a method, how to descend the air from the heating radiator or, if necessary, from the pipeline.

The air cork not only prevents the circulation of the coolant, but provokes corrosion of metal pipes. The presence of air in the system negatively affects the operation of the circulation pump.

Where the air appears in the system

The reasons for the formation of air traffic can be both natural and associated with improper design of the system and poor quality installation.

Naturally emerging reasons:

when heating the coolant is released dissolved in the liquid air, it rises up and forms a plug;
gas bubbles appear in the process of reacting hot heat carrier with some types of metals (in particular, aluminum);
due to evaporation, the liquid level in the open expansion tank is reduced below the critical value;
air does not have time to completely exit pipes and batteries when it is too fast filling with water difficult to configure the system.

It is important to know how to pull water from the heating system if necessary and then fill it again so that in this case, the air remains in the pipelines and radiators.

In addition to natural reasons, the appearance of air traffic jams also leads:

incorrect layout of horizontal pipes and installation of radiators;
pressure drops in the feeding water supply;
poorly sealed compounds;
worn out of old pipelines;
fault of the expansion tank.

When during the operation of the heating system, it turns out that it was originally designed incorrectly, it would have to redo it. But to urgently restore the flow of heat, you need to decide how to pull the air from the heating system.

Elimination of air traffic jam

If the heating is properly designed, then how to pull the air out of it, will not be labor. You can arrange so that the booming air blending will occur automatically, as it accumulates. For this serve special devices - air vents installed at critical points. In other cases, you need to purchase skills, how to lower the air from the heating system in manual mode.

It matters:

open or closed system type;
natural or forced coolant circulation;
upper or lower version of pipe wiring;
are the slopes of pipes horizontally compliant.

Radiator Radiant Crane

In apartment buildings, residents do not have a question how to pull the air from heating, the specialists of the management company should be worried about it. Although the heating is so arranged in the old five-story buildings that it is possible to pull the air from it only through the radiator in the apartment of the upper floor, and this periodically accounted for the tenants. More acute the problem of mapping for owners of private houses, having autonomous heating - the air is periodically necessary to pull the air. To lower the air from the radiator of water heating, the needle air valve is used, the so-called. Crane Maevsky. Such a device is installed in the upper end of the radiator battery, instead of a plug. Sometimes it is also used to descend the air from the tube of the heated towel rail. Various models of Maevsky cranes are somewhat different, so before you pull the air in heating radiators, you need to get acquainted with the instructions. Open the valve of the crane or a horn key, or a conventional screwdriver, or just with hand.

Consider how to drain the air stop from the heating battery with the help of Maevsky's crane installed on it:

prepare tools (key or screwdriver) and water collection capacity;
open a completely thermostat, then unscrew the crane of Maevsky to the half turn;
air will begin to go through the valve with a slight hiss;
substitute the container and keep the valve open, as it is necessary to lower the air from the heating radiator until water flows;
when a dense weaping of water can be tightened.

If, after you lowered the air from the heating battery, it is still poorly heated, drain through the same crane of the 200 coolant gram to finally remove the air stopper.

Sitting the air through the expansion tank

In private houses, the device of heating systems can be different, it depends on the features of the planning of buildings. For different types of systems, appropriate expansion tanks are used - open or closed. Therefore, individual homeowners more often have to think about how it is more expedient - to lower the air from the heating radiator or through the expansion tank .

In the open type system, air bubbles have free output through the expansion tank installed in the attic. If the heating is working normally, the air from the system is not necessary, since it comes out itself. But the liquid gradually evaporates, and the water level in the open expansion tank can fall so low that an air stopper will appear at the top of the feed pipeline. In this case, the circulation of the coolant will slow down or completely stop, and in this situation it should be about how to pull the air from the heating system.

To drive out an air stopper, you can add water to the expansion tank on top, but it is better to replenish the volume of fluid in the system through the bottom crane connected to the water supply system. The water coming from below will fill the emptiness in the pipe and squeeze the air out through the opening of the expansion tank.

During the heating season, it is necessary to ensure that the expansion tank is constantly filled with water by approximately 2/3 of the volume, and with a decrease in the level of water.

In closed systems, membrane expansion tanks are used. Sometimes there is a break of the membrane, and then the air is entering the system. If it is possible to establish that the reason for carrying is a faulty expansion tank, it will have to be replaced. But before starting repair, before the water from the heating system, you need to prepare everything you need to leave the house for a long time without heat.

What should be the right system of the system

When designing, it should be envisaged that air can accumulate in horizontal pipes, and how to pull it from the heating system will be a difficult task. Therefore, it is important that the top feed pipe has a small bias, ranging from the riser and then along the movement of the coolant. At the highest point, a device is installed that allows you to lower the air from heating. It can be a regular crane or crane Maevsky, but it is better to use an automatic air vent. In a more complex configuration, the heating system the air vents are mounted in all places where the problem of vesting can occur. Then the question will not arise how to lower the air in one or more heating radiators, since the accumulating bubbles will be pulled out from each group of the components of the system of elements.

The return pipe must be laid with a slope towards the boiler. This is done to combat air traffic jams, as well as in order not to guess what way to pull water from the heating system when repairing the repair.

If the heating system is equipped with a circulating pump, then there is no need to comply with the slope of pipes. And yet, for the efficiency of the system, it is desirable to lay pipelines with the right slope.

Finally, you can recommend that you always apply to specialists about problems with heating. They know how to design a working system and advise how to pull the air accumulated in heating radiators. But the homeowners themselves should have the on the eve of the heating season to produce a prophylactic inspection and verification of their heating system.

Removing air traffic jams from the heating system: how to lower the air from the radiators?

Air in the heating system is an obstacle to its normal functioning. With this problem, residents of apartments and houses face, as a rule, at the beginning of the heating season. Noise in pipes, cold batteries, corrosion of metal elements - this is the result of the formation of air traffic jams. And this happens even with a perfectly designed and properly mounted heating system. Why this happens and for what it is necessary to make air removal from the heating system in a timely manner - this will be discussed in this article.

Why does air appear in the heating system?

Many of our compatriots are familiar with the concept of "air traffic jams". This phenomenon is remembered at the beginning of the heating season, when warmth is drunk in the houses, and in the apartments of the upper floors, the batteries are often not heated or heated only at the bottom, and in the upper - absolutely cold. Where does the air appear in the pipelines? The reasons for bringing may be several:

repair work (assembly, disassembly of the pipeline), during which air appearance is inevitable;
non-compliance during installation of the magnitude and direction of the linker of pipelines;
reduced pressure in the water supply: water level falls, and the resulting voids are filled with air;
when water heated, the bubbles contained in it are highlighted and rising into the upper part of the pipeline, creating air traffic jams there;
the heating system is incorrect: after summer downtime, the pipes should be filled with water not quickly, and slowly, producing simultaneously moving the air from the heating system;
unsatisfactoryly sealed joints of pipelines through which the coolant leak occurs. The flow in these places is unlikely to flow, since hot water is immediately evaporated. It is through loose seams and air to the system is suused;
fault air intake devices;
connecting water "warm floor" to the heating system whose pipes are located at different heights.

Air traffic removal methods

Since one or more of the listed factors may be present in many homes, then the issue of air removal in the heating system necessarily faces. This operation can be performed in various ways. It all depends on which circulation of the coolant is dealing - natural or forced.

In the heating system with natural circulation (meaning the upper pipe wiring), the resulting air plug can be removed through the expansion tank - it is in the highest point in relation to the entire system. The supply of the feed pipe should be made with a lift to the expansion tank. With the lower layout of the pipes, the air is removed in the same way as in heating systems equipped with a circulation pump.

Wash air from the heating system with natural circulation using the expansion tank

In heating systems with a coercive coolant circulation mode at the highest point, an air collector is installed, specially provided for the air descent. In this case, the feed pipe is paved with the rise in the coolant rate, and the air bubble-rising bubbles are removed through air cranes (they are installed at the highest points). In all cases, the return pipe must be laid with a slope in the direction of draining water for accelerated emptying if repairs are needed.

Types of airlighteople and places of their installation

The air vents are manual and automatic. Manual air ventures or cranes of Maevsky have small sizes. They are usually installed on the end of the heating radiator. Regulate the crane of the Maevsky using the key, screwdriver or even manually. Since the crane is small, then its productivity is small, so it is used only for local elimination of air traffic jams in the heating system.

The air vents for the heating system are two types: manual (crane Maevsky) and automatic (work without human participation).

The second type of air vent - automatic - work without interfering. They are installed both in a vertical position and horizontal. They have high performance, but have a sufficiently large sensitivity to pollution in water, so they are mounted along with filters and on feed pipelines, and on the reverse.

Automatic air vents are installed in the heating systems of a closed type through the line of pipelines at different points. Then the reset of air from each group of devices is made separately. The multi-stage monitoring system is considered the most efficient. With proper laying and competent installation of pipes (under the desired slope), remove the air through the air ventures will simply and trouble-free. Removal of air from heating pipes is associated with an increase in the coolant consumption, as well as with an increase in pressure in them. The water pressure drop indicates a violation of the system's tightness, and temperature differences - the presence of air in heating radiators.

Determination of the placement of traffic jam and its removal

How can you understand that there is air in the radiator? Usually, the presence of air indicates outside sounds, such as bouffaging, water flow. To ensure a full circulation of the coolant, it is necessary to remove this air. With full recent system, it is necessary to determine first the place of formation of traffic jams, tapping the hammer over heating devices. Where there is an air traffic jam, the sound will be more ringing and strong. Air is assembled, as a rule, in radiators installed on the upper floors.

Using that the air in the heating device is present, you should take a screwdriver or key and prepare water tank. Opening the thermostat to the maximum level, you need to open the valve of the crane of Maevsky and substitute the container. The appearance of light hissing will mean that the air comes out. The valve is kept open until water flows and only then closed.

Elimination of air traffic jams in the heating battery using the Maevsky crane installed on it: the valve opens with a special key or manually and kept open until water

It happens that after this procedure, the battery warms not long or not enough. Then it needs to be purged and rinsed, since the accumulation of garbage and rust can also cause air appearance.

If, after the air shutter, the battery is still badly heated, try to merge about a 200g of the coolant to make sure the air traffic jam is performed. If it did not help, but it is necessary to blow and rinse the radiator from possibly accumulated dirt

If after that there is no improvement, you need to check the level of filling the heating system. Air traffic jams can also be formed on pipe bends. Therefore, it is important in the installation process to observe the direction and the magnitude of the bias of laying pipelines. In places where the bias for any reason differs from the project, additionally install aircraft valves.

In aluminum radiators, air traffic jams are formed more intensively due to poor quality material. As a result of the aluminum reaction with the coolant, gases are formed, so they must be regularly removed from the system. In such situations, it is recommended to replace aluminum radiators to devices from better-quality materials with anti-corrosion coating and install air vent. In order for the heating of the rooms is normal, before filling in the heating system with water, it is necessary to take care of the removal of air that impede the normal movement of the coolant from it, and then in winter in your house will be warm and cozy.

How to lower the air from the battery if there is no crane Maevsky

Most often with the heating system in the house there are no problems. But sometimes suddenly in the house becomes cold or strange sounds arise in the heating radiator. What can it be? Unfortunately, in this case there is air in the heating system, which means that air is needed from there. Today you will learn how to do it without crane Maevsky.

Enforcement in the battery: what it is and how to determine

Carrying out repair work on the site / in the neighboring floors. In case, in a residential square, work with heating pipes were carried out, the likelihood of a small air flow system was large.
There was a leakage of the coolant on some of the sites (which means immediate checking system to eliminate leakage).
Feature of the system of warm floors. The problem of the enforcement system is indeed a frequent pattern in the presence of a warm floor system, especially if it has a complicated scheme and many branches.

In water having a high temperature, air is contained and the more often the coolant is updated in the system, the higher the probability of a malfunction.
If the appearance of the air "traffic jam" coincides with the launch of the overall heating line - with a greater share of the probability, it is possible to say that it is the start of the system that caused recent.

Council. If you live in a private house, then, in principle, it is not necessary to get hard to worry about the enforcement of the system (if it is small), the fact is that in private heating systems most often the coolant changes extremely rarely, and it means that the air must be independently scribified within a few days.

Rest of air without crane Maevsky

On most home heating batteries, there is a special device that helps as easier to simplify the task of air boom - the crane of the Maevsky or automatic valve.

But here is the question: what to do, if such a device is simply missing on the battery? If you just like this picture before your eyes - most likely, cast iron batteries are installed in your house. On such batteries, a simple plug is often installed, which was spinled on the pack-covered panel. In addition, it was also filled with a layer of paints during the staining of heating batteries.

You learned about how quickly and quite simply can be copped with the task of moving the air from the radiator of heating in the absence of the crane of Maevsky. Good luck!
